-T 1f/ZZ 'whom it 11mg concern:

Be it known that I, JOHN HANDscHU- MACHER, a citizen of Austria, residing at San Francisco, in the county of- San FranciscoY and State of California, have invented certain new and useful Improvements in Sliding Doors, of which the following is a specifica-` tion.

My invention relates to improvements in sliding doors. In such doors as at present constructed there is a considerable opening between the top of the doorv and the jamb therefor.

-plumb and also in the plane of the doorlthe door with the hanger-arm.

frame. Also I provide a, construction by which the door can be placed in position after all the finish of the jamb has been put on and can also be easily removed from said jamb.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis a side elevation of my improved sliding door,

the jamb'being broken away to showV the conl struction of the hangers and of the connections thereof with thedoor. Fig. 2 is an enlarged vertical section of the connection of Fig. 3 is a vertical section on the line AA of Fig. 1. Figs. 4, 5, and 6 are cross-sections of Fig. 2 on the lines B B, C C, and D D, respectively. Fig. 7 is a horizontal section` on the -line X X of Fig. 3. Figs. 8 and 9 are views, similar to Figs. 1 and 2, of a modified form of the invention. Fig. 10 is a vertical section on the line E E of Fig. 8. Figs. 11, 12, and 13 are cross-sections of Fig. 9 on the lines F F, G G, and H H, respectively. Fig. 14 is a rear view of one of the hangers in this modification, the beam being broken away; and Fig. lisadetail showing a special form ofwrench for screwing and unscrewing the nuts.

door, and b the jamb therefor.

Referring to the drawings, a represents the At the top said jamb comprises the studs c, the rough headers d, secured to the lower ends of said studs, and the jamb-header e, secured on the under side of said rough headers. To the studs c on one side is'secred a beam f, which is rabbeted at its upper edge, as shown at g, and to which Vis attached rthe track h. In former constructions the track has been secured directly to the studs and was therefore liable to delectionwhen said studs deviated Vter tothe single front hanger m, and in the slots of said front plates roll the axles of the two wheels i, while the rear plates Z are rigidly attached at their ends to the two rear` hangers n, and in the slots of said rear plates rolls the axle of.' a single wheel t'. The hangers m n are attached to ahanger-arm o, the

rearhangers n beingrgidlyattached to said arm,while the front hanger m is adj ustably attached by means of a screwp, working in the threaded free end of said hanger-arm o. The

head of said screw has notches q cut inits edge, and the jamb-header e has a hole r cut therein at any desired point, through which access is had to said notches q when the upper jambs is removed. By screwing up or down said screw p the front ,edge of the door, corresponding to the-free endof the hanger-arm, may be raised or lowered, as desired, to suspend the vdoor plumb.

To the hanger-arm o is suspended, by means of a nut t, a stem It, threaded in its lower portion, as shown at c, and carrying on said threaded portion a nut w, supporting a sleeve rc.- By screwing said nut upor down on the stem u the sleeve :c may be raised er lowered to bring the door into close proximity with or away from the jambheader.-

The door is supported upon the sleeve .fr by means of a plate y, countersunk on the top edge of the door and attached to the door and having a socket e at its end contracted, as at l, to fit around the stem u and rest upon the top of the sleeve and enlarged, as at 2,

IOO

to [it around said sleeve. Said socket is open at its rear side, as shown at 3, said opening being, however, less than a semicircumference in the upper portion; but as said socket is cut away obliquely in its lower portion, as shown at 4, the opening in the rear is greater than a sem'icircumference in the lower portion of the socket. Therefore when the sleeve a: is lowered by screwing the nut w down-l ward the door may be withdrawn from the stem and sleeve. A vertical plate 5 is secured to the inner edge of the door'and also to the socket-piece z, and to said plate 5 is secured an abutment 6, against which the sleeve arrests, forming a guide for said sleevev as it is moved up or down.

When it vis desired to 'remove the door, all that is necessary is to remove the upper jamb s and rear side jamb 7, to permit the door to be swung around the sleeve w o ut of its normalplaueof reciprocation and then to screw down the nut w until the sleeve w drops down a sufficient distance to enable the, opening 3 in the rear of the sockets to move past said sleeve 0c.

A n important feature of my invention re,`

sides in the construction, wherebyfa hanger can be removed from the .lamb and repaired or another hanger substituted therefor with,- out tearing down any part of the jamb to get at said hanger.

ter of the wall inwhich the door slides.'

Withm-y construction the necessity for this is obv-iated and they hanger can he removed merely hy looseningthe screws which secure the hanger to the hanger-arm. This can be done by removing the, door and then moving the hangers along the track intol tlie recess intowhich the door slides.

The. nut w has pertorations 8, by means of which i-t caribe turned in either d'1 fectionby meansk of a hook,l In order toinsure a tight union between th stem` u and the` hanger-arm o, the upper end of said steml is made conical or tapering, as shown at 9, and itsint an upwardly-tapering socket in the endet the hanger-arm o.4 By screwingdown thenutt the tapering end of the stem uis forced firmly intofthe socket in thehanger-arm,thusinsuringati-ght j oint.`

A set-screw l0, the head of which may be covered with rubber,y if desi-red, is provided, attached tok thesocket z,thepurpo,seot which ment of the door to close the same, this being of especial advantage for a pair of dou-ole doors. A rubber stopll is likewise usedl to vlimit the movement in the opposite,direction.`

In the modification shown in Figs. 8 to 14:A only a single roller is used for earch hanger-` The front hanger is bent inward' to form a horizontal flange 12, through which are thev plate 5.

v rotate the same.

In thepresent construction of sliding doors it is found necessary to rescrewed vertical screws 1 3,y passed `through the hanger-arm. Through said flange is also screweda third screw 14, the end of which comes into close proximity with the under side of the track h and prevents the front wheel jumping upward from the track. In this modification to the lower end of the stem u, is rigidly attached a block 15, into which are passed two screws 16, passed through vertically-slotted holes 17 in a bent portion 19 of By means of these screws the door may be brought into the same plane as the door-jamb, since by screwing in a screw on either side and'unscrewing the screw on the other side the horizontal direction of the door may be varied at pleasure. 20 represents leather rings interposed between the ends of modification the'nutst and w have sockeiSQl in theirperiphery, and in Fig. 15 Ihave shown a special form of wrench for turning the nuts t and w. Said wrench comprises abent han-V die 22,'having adjustably secured thereto an arm 23" the point of,` which can enter one of the sockets 21 in the nuts t and w, and thereby The arm 23 can be turned to any direction in relation to the handle 22 and there secured or tightened by means of the screw 24- I; claim-l 1.
